In particular, the public service node 5 can be configured to perform: sign step: sign the electronic evidence with a private key from the public service subchain to obtain the service signature data. As shown the , there are n public service nodes, where n can be any positive integer, and the corresponding service signature data obtained are: service signature data 1, service signature data 2, ..., signature data service n. The service signature data may be a justice signature as electronic evidence given by a justice institution, or a surveillance signature signed by a surveillance institution. As an example, E represents an electronic proof, the private key of the public service subchain can include the private keys from public service node 1 to public service node n, which are respectively k1, k2, .. ., kn, and the signatures of the electronic evidence corresponding to the public service node 1 to the public service node n are: S k1 (E), S k2 (E), ..., S kn (E). [0029] Additionally, the electronic evidence platform 1 is further configured to perform: collective sign step: collectively sign the service signature data to obtain collective signature data. The collective signature may add, multiply or assemble plural service signature data to form collective signature data, and the specified mode of the collective signature shall not be limited by this application. By way of example, G can represent collective signature data, ie G=[S k1 (E),S k2 (E),...,S kn (E)]. [0030] At the step of generating an abstract, perform a hashing operation on the collective signature data to obtain a digital abstract; At the evidence escrow stage, send collective signature data, digital abstract, evidence signature and timestamp to blockchain digital evidence registration platform.
